What It Does
Stealthly is an AI text humanizer that rewrites AI-generated content to make it resemble human writing. Its stated audience includes students, writers, agencies, webmasters, and SEO professionals who want to modify AI-assisted drafts while retaining their original meaning.
A typical workflow starts by pasting AI-generated text into Stealthly, selecting one of three humanization modes (Light, Balanced, or Deep), and running the humanizer. The resulting text is intended to retain the original meaning while changing wording, structure, and linguistic patterns to produce a more human-like version.
